Do Ultraviolet Air Disinfection Units Reduce Contamination by Particulates in Total Knee Replacement Procedures?

Background: Prosthetic joint infections have become the leading cause of joint replacement failure. The primary sources of contamination are skin flora and bacteria from airborne particles. Portable ultraviolet air disinfection units are used in the Operating Room (OR) to prevent contamination from airborne particles; however, their effectiveness is not proven.

Humanitarian Needs: The Arthroplasty Community and the COVID-19 Pandemic.

Background: As the world struggles with the COVID-19 pandemic, health care providers are on the front lines. We highlight the value of engaging in humanitarian medical work, contributions of the hip and knee arthroplasty community to date, and future needs after the resolution of the pandemic. We sought to understand how the arthroplasty community can contribute, based on historical lessons from prior pandemics and recessions, current needs, and projections of the COVID-19 impact.

Robotics in Orthopedics: A Brave New World.

Patient Preference Before and After Arthroscopic Rotator Cuff Repair: Which Is More Important, Pain Relief or Strength Return?

Our understanding of patients' desired outcomes and expectations of arthroscopic rotator cuff repair (ARCR) is limited, particularly regarding the importance of pain relief and strength return relative to each other. We conducted a study of patient's ratings of the importance of pain relief and strength return after ARCR. Before undergoing surgery, 60 patients completed a shoulder questionnaire on which they assessed severity of symptoms and rated, on a 10-point scale, the importance of postoperative improvements in pain relief and strength return.
